EVERETT C. LEWIS, 0F SEEKONK, MASSACHUSETTS, ASSIGNOR TO UNIVERSALWINDING COMPANY, OF PORTLAND, MAINE, A CORPORATION OF MAINE.

WINDING-MACHINE.

Specification of Letters Patent.

To all whom it may concern Be it known that I, EVERETT C. LEWIS, acitizen of the United States, residing at Seekonk, in the county ofBristol and State of Massachusetts, have invented certain new and usefulImprovements in Winding-Machines, of which the following is aspecification.

My invention relates to improvements in winding machines and consistsparticularly of a novel arrangement of mechanism for releasing anddoflin the completed cop or package from the winding spindle.

The object of my improvement is to provide means for utilizing the powerwhich drives the machine to force the package oif from the spindle, sothat the dofiing may be done more easily and expeditiously, and withoutdanger of injury to the package or the material therein.

The invention is fully set forth in the following specification,illustrated by the accompanying drawings, in which z.

Figure 1 is a plan view of a winding machine, showing my new deviceapplied thereto; Fig. 2, a front elevation ofthe same, part sectional onthe line X -X of Fig. 1; Fig. 3, an end elevation, looking in thedirection indicated by the arrow a, Fig. 1; Fig. 4, a sectional view ofthe spindle bearings and cop-tube, taken longitudinally, andillustrating the manner of releasing the tube and dofiing the package.

My invention is particularly adapted for use on winding machinesemployed for winding cord, twine, rope and other heavy and strongmaterials. It is the general practice to 'wind such materials intorelatively large packages for commercial purposes and the cheapest andmost practical form of support for such a package is the well knownpaper or fiber cop-tube, socalled. The cop-tube is usually held in thewinding machine on a rotating mandrel or spindle extending through itand as the layers of winding are built up to form the package the tubeis subjected to great pressure, owing to the constriction of the coilswhich are laid on under heavy tension.

This constrictive action of the winding causes thetube to contract andbind on the mandrel to such an extent that it is often a difficultmatter to get it off, and frequently the package will be broken down anddamaged in attempting to dofi it. My new invention provides forutilizing the'power of the machine for forcing the cop-tube off themandrel and thereby the dofiing canbe accomplished with greater ease anddespatch and without danger of injury to the package.

Referring first to Figs. 1 and 2, B designates the frame of the windingmachine which is provided with bearings Z), I) for the main drivingshaft C, and opposite bearings Z1 b for the traverse-cam shaft D. Theshaft G is hollow, as shown in Fig. 2, and carries the belt pulleys Eand E. The pulley E is held fast on the shaft 0 by the set-screw e andserves to operate the whole machine from the power transmitted through asuitable driving belt, not here shown. The pulle g. is adapted to rotatefree on the shaft 8 etween the hub of the pulley E and the bearing 6andserves as an idler on to which the belt is shifted when it is desiredto arrest the operation of the machine.

The shaft C is formed at one end with a. flange c abutting the end ofthe bearing 6 to take the thrust of the shaft in one direc' tion, and apulley F, secured to the shaft by a set screw 7 with its hub abuttingthe opposite end of the bearing 6 prevents longitudinal movement of theshaft C in the opposite direction. The ulley F is connected to a pulleyG on t e shaft D by a belt 9 to adapt the two shafts to rotate together.An adjustable idler-pulley H is arranged to bear on the top of the belt9 between the two pulleys F, G to keep the belt tight and preventslippage. Preferably the pulley F isof the expansible type, now wellknown in the art, to provide for adjustment of its diameter so that thespeed of the two shafts can be varied in relation to each other toregulate the spacing of the coils of winding; but as this feature of themachine forms no part of the present invention it will not be describedin detail.

Mounted on the end of the shaft D and rotated thereby is a screw-shaftor cam J Patented Jan. 26, 1915.

having a double-helical groove formed in its periphery. A carriage orslide K is fitted to the cam J and adapted to slide back and forththereon, being reciprocated by a shoe or runner 7:: which engages withthe cam-groove j. The slide K has an arm or extension Z" carrying abushing which slides on a rod O supported on an overhanging portion ofthe frame B of the machine, arallid with the axiof the cam J. An arm Lwhich serves as a twine-guide'is formed with a forked end l straddlingthe extension 70 and pivoted on the bushing 70 The arm L is providedwith rolls on grooved pulleys l and Z over which the twine t draws as itleads to the winding spindle, the tension on the material acting toizeep the end Z of the guide-arm bearing on the winding. The guide-arm Lis caused to traverse the wind ing spindle through the reciprocatingmotion imparted to the slide K by the cam J and as the package increasesin diameter the arm L swings on its pivot to allow the guiding end Z torecede from the spindle.

The winding spindle or' mandrel S which supports the cop-tube m on whichthe winding is performed is constructed as a telescopic extension of thehollow shaft C, being fitted to the bore of the latter and adapted toslide longitudinally therein, see Fig. 2. At the outer end of the shaftG is secured a sleeve or bushing 0 which serves to locate the cop-tube win position on the spindle S and also acts as a pusher to force the tubeolf when the spindle is retracted, as more fully explained hereinafter.During the winding operation of the machine the spindle S is in aforward position, as shown in Fig. 1, and its outer end is supported byan outboard bearing arranged as now described: A bracket B extends fromthe side of the main frame B of the machine and projecting from the endthereof is an arm B see Fig. 1. The arm B is preferably supported at itsend by a rod u reaching to the floor, see Fig. 2, and is formed'with abearing 1) in which a bushing M is adapted to rotate. Adapted to rotatewith the bushing M and arranged to slide longitudinally therein is alive spindle S having its axis in line with that of the spindle S andserving as an extension thereof.

The spindle S is reduced in diameter at 3 throughout a portion of itslength and again at its end and carries a hand-knob N secured to thisend by a transverse pin n.

The bushing M is formedv with a flange m abutting the inner face of thebearing 1) and a cap or collar m is fastenedto its opposite end andbears against the outer face of the hearing so that the bushing is heldfrom longitudinal movement. Preferably, the cap m is secured to thebushing M by screws 0. 0 which are formed with extensions reaching clearthrough the bushing the spindle-extension S.

spindle S is provided with an axial hole .9

and formed with radially disposed ratchet teeth 8 The opposing end ofthe spindle S is also formed with corresponding teeth 8 adapted toengage the teeth s and an axial.

stud or pintle 8 projects therefrom and is adapted to engage the hole 8\Vhen the spindle S is in its forward position. as illustrated in Fig.1, its end will abut the end of the spindleextension S and engage thelatter so that they both rotate as one. The screws 0, through theirengagement with the splines 8, cause the bushing M to rotate with thespindle-extension S and through this arrangement the outer end of thespindl'e S is suitably supported to take the weight of the package andresist the pull of the twine as it is wound on to the tube an undertension. The spindleextension S is also susceptible of being drawnoutward in the bushing M for a purpose later described.

It is also to be noted that the tip end s" of the spindle S is slightlyreduced in diameter from that of the main portion and corresponds indiameter to the projecting end of This diameter is slightly less thanthat of the bore of the cop-tube .r to provide that the ends of bothportions of the spindle will not stick or bind in the tube when the mainspindle S is retracted as shown in Fig. 2. 7

The spindle S is screw-threaded from its opposite end throughoutapproximately onehalf its length and, normally, the greater part of thisthreaded portion lies within the shaft C. It will also be observed byreference to Fig. 2 that this screw-threaded portion s of the spindle Sis formed with a key-way or spline s which is engaged by a key 0 securedin the end of the shaft C. This provides that the shaft C and spindle Swi'llbe rotated together from the driving pulley E to rotate thecop-tube w and wind on the material.

A small portion of the threaded end of the spindle S projects from theend of the shaft C when its opposite end is in engagement with theextensionS, as shown in Fig. 1, and at its extremity is secured a cap orcollar R formed with a flange 1'. Normally, this flange 1" is engaged bythe crescent-shaped extension r of a lever V which is formed with apocket 1: adapted to receive the flange, see Fig. This ongagement actsto prevent the spindle S from sliding in the shaft in either directionand maintains it in its normal position during the winding. The lever Vis also provided with a half-nut 2: adapted to be carried intoengagement with the threads on the spindle S to cause the retraction ofthe spindle within the shaft C. as more fully explained hereinafter.ferring to Fig. 2. it is to be noted that the spindle S is reduced indiameter at s so that the halfnut will ride on this portion of thespindle after the threaded portion has passed through the nut.Preferably the lever Y is secured by a pin '0 to the end of a rod orrock-shaft W mounted in bearings I). I) in the main frame B of the machine. it its opposite end the rod \V is bent at right-angles andextends upwardly between the winding spindle and cam-shaft to provide ahandle 1/. for operating the lever V manually. Collars w and u aresecured to the rod \V adjacent the bearings If and I)? to hold the rodfrom longitudinal movement and between the collar to and the hub r ofthe lever V is a coiled spring ;I One end of the spring 7 is secured ina hole 1' of the hub '0". see Fig. 2, and its opposite end extendsthrough a hole I) in a rib 71 which projects from the side of the frameB. see Fig. 3. The torsion of the spring 1 tends to rock the rod W andswing the lever V in the direction indicated by the arrow 2, Fig. 3. tocarry the nut v away from the spindle S. A pin 2 driven into the frame Blimits the movement of the lever V in this direction and maintains it inposition for the extension r to engage the flange r with a clearance'between the periphery of the flange and-the bottom of the pocket 1*.This arrangement prevents the action of the spring 3/ from causing thetension 0 to bear against the periphery of the flange and cause unduewear on the engaging parts.

The operation of the whole machine is as follows: Before thecommencement of the winding parts will be in a position as illustratedin Fig. The cop-tube to, represented in Fig. by dot-and-dash lines. isplaced in position by first withdrawing the spindleextension S from itsnormal position. This is performed by grasping the hand-knob N andpulling it back against the action of the spring 1. and the tube 11' canthen be placed in position with one end resting on the tip end a of themain spindle S. see Fig. 4. The knob N is then released to allow thespindle-extension S to enter the opposite end of the tube as shown inFig. 2. The handle it: is next moved forward slightly to carry the leverV into a neutral position with the extension '0 clear of the flange 1'and the nut r free from the threads on the spindle S. The spindle S canthen be thrust forward through the shaft and into the tube .2 until itsend abuts the end of the spindle-extension S with the pintle s engagingthe hole s and the teeth 8 engaging the teeth a to form practically onecontinuous shaft. The halldle w is now released and the spring 3 willcarry the lever V into position for the extension r to engage the flange2", as shown in Figs. 1 and 3. 'The sides of the extension i of thelever V abuts both sides of the flange 1" to maintain the spindle S fromlongitudinal movement and the machine is now ready for operation. Thetwine t is led up from its supply to the guide-arm L and drawn over theguide-rolls Z and Z whence it is fed to the winding spindle. After theend of the twine has been secured to the cop-tube .12 the belt isshifted from the loose pulley E on to the driving pulley E and themachine starts to operate. The pulley E drives the shaft C, which.through the key 0, rotates the spindle S. and .the cop-tube is turned towind on the material. Usually the tube .2 fits the spindle S so snuglythat it will turn with it without theneed of holding means. but. ifrequired, suitable holding devices such as expanding springs or ribsmight be pr0- vided to grip the interior of the tube.

The shaft D is driven from the shaft (f through the pulleys F. G andbelt 9 and the cam J rotates therewith to reciprocate the guide-arm L.The traverse of the g'uide arm acts to deposit the coils of winding onthe cop-tube in superin'iposed layers and the package is built up tosubstantially the proportions illustrated by dot-and-dash lines ineither Fig. 1 or Fig. l.

\Vhen the package reaches its predetermined size and is ready to bedotted from the winding spindle the handle w is grasped by the operatorand carried forward in the direction indicated by the arrow 3, Fig. 3.This brings the half-nut r into engagement with the threads 8* on thespindle S and the rotation of the latter will cause it to feed backthrough the nut in the direction indi cated by the arrow 4, Fig. Thespindle S is thus retracted within the shaft C and during its movementthe end of the sleeve 0 engages the end of the cop-tube a: and as thespindle S is withdrawn Within the sleeve the latter acts to hold thetube until it is forced free of the main portion of the spindle andsimply rests upon the reduced tip-end 8 see Fig. 2. The opposite end ofthe cop-tube .21 will still remain supported on the end of the spindle Sand in this way the package is prevented from falling on the floor andbecoming damaged. After the screw-threaded portion of the spindle S hasfed completely through the nut 19 the latter will ride on the reducedportion 8 and no further movement of the spindle will be effected. Thehandle in can now be released and the driw ing belt is shifted on to theloose pulley E to arrest the operation of the mechanism. To remove thepackage from the machine it is now only necessary to pull out thehandknob' N, as shown in Fig. 4, to withdraw the spindle-extensions fromthe outer end of the tube 00 and the opposite end of the coptube canthen. be drawn off the end of the spindle S. The ends of the spindle Sand spindle-extension S being of slightly less diameter than the bore ofthe tube 00, as before explained, it will be seen that the tube will notpinch or bind at these points, but can be easily slipped off. After thedoffing of the completed package the parts of the mechanism are inposition to receive a new cop-tube which can be quickly applied asbefore explained.

It will be seen that my new device provides a convenient and easilyoperated means for applying the cop-tubes to the winding spindle and forautomatically dofling the completed package without manual labor andwithout pressure against the ends of the package, thereby removing alldanger of damage to the package itself or injury to the material ofwhich it is composed.
